RHBA-2011:1474 - Bug Fix Advisory

Topic

An updated iprutils package that fixes multiple bugs is now available for Red
Hat Enterprise Linux 6.

Description

The iprutils package provides utilities to manage and configure SCSI devices
that are supported by the IBM Power RAID SCSI storage device driver.

This update fixes the following bugs:

• Due to an incorrectly placed call of the sysfs_close_bus() structure in the

iprlib code, some of the iprutils programs could terminate unexpectedly with a
segmentation fault during their initialization. This problem has been corrected,
and iprutils programs no longer crash. (BZ#747621)

• The find_multipath_vset routine used the ARRAY_SIZE() macro to calculate the

length of the SCSI device serial number. Previously, the length was calculated
incorrectly, which could have led to false positives when looking for the
corresponding vset. As a consequence, attempting to delete arrays failed: the
target and the second array were set to be read/write protected, writing to both
arrays was not possible, and the system had to be rebooted. To fix the problem,
the IPR_SERIAL_NUM_LEN macro is now used instead of ARRAY_SIZE. (BZ#747621)

• With the maximum number of devices attached to one of the new Silicon

Integrated Systems (SiS) 64-bit adapters, the configuration data could have
grown over the buffer size. With this update, the buffer size has been
increased, which fixes the problem and ensures enough space for any possible
future growth. (BZ#747621)

All users of iprutils are advised to upgrade to this updated package, which
fixes these bugs.
